The National Institute of Health’s ClinVar public database of genetic variation is demonstrating good accuracy, and a handful of clinical labs are learning to share and review this relatively small genetic database
In the analysis of genomic variants, data sharing is proving to be an important tool for researchers, scientists, pathologists, and clinical laboratory scientists.
Accessible databases like ClinVar, which was launched by the National Institute of Health (NIH) in 2013, have emerged to aggregate genetic sequencing with acceptable results. ClinVar exists to meet the needs of the medical genetics community. It collaborates with organizations to make pertinent genetic information available.
ClinVar is an archive of compiled data relating to genotype and phenotype variations among humans. Through this database, individuals can present and peruse submissions regarding variants found in patient samples.
ClinVar is averaging about 6,000 submissions per month by both commercial laboratory companies and reference labs. Major contributors to the database include: (more…)

Researchers are concerned about the lesser-known genes included in the test and also point out that little published research exists to support use of these genes for clinical laboratory testing
Gene-panel tests for inherited cancers were scrutinized by a group of 17 prominent international genetic researchers in a study published by the New England Journal of Medicine (NEJM) this summer titled “Gene-Panel Sequencing and the Prediction of Breast-Cancer Risk.” These experts pointed out that, for many of the genes included in these test panels, there remains much uncertainty about their role in various cancers and other diseases.
What will be of greatest interest to pathologist, Ph.D.s, and medical laboratory professionals currently performing molecular diagnostics assays and genetics is that these experts proposed greater regulation of unvalidated gene-panel tests for inherited cancers. In the NEJM, the authors provided some examples of genetic tests, such as those offered by Myriad Genetics, Inc. (NASDAQ:MYGN), Ambry Genetics, Invitae (NYSE:NVTA), and Illumina, Inc. (NASDAQ:ILMN) and noted that risks posed by many mutations occurring on these panels are unknown.
These panel tests can include more than 100 genes, 21 of which are an indication of breast cancer, including BRCA1 and BRCA2, stated the paper. (more…)

More precise diagnoses will encourage pathologists and clinical laboratory professionals to consider using exome sequencing for clinical diagnostic purposes
Having sequenced the exomes of 150 patients to diagnose unknown disorders over the past year, physicians at Columbia University (CU) used that information to make decisive diagnoses in one-third of the cases. It is evidence from one of the nation’s pioneering gene-sequencing programs that such data can improve how physicians identify disease.
Findings from Exome Sequencing Program Noteworthy for Pathologists
Pathologists will find it noteworthy that some of the patients in the exome-sequencing program had been tracked for years at CU without a definitive diagnosis. This is why clinicians at the academic center in New York City see value in exome sequencing for selected patients.
For more than a year, doctors at Columbia University have tested the exome’s capability to provide a correct diagnosis for patients with suspected genetic disorders of unknown origins. The primary goal of the program is to prove that sequencing the exomes of these patients is both clinically useful and cost effective in guiding physicians to a correct diagnosis. (more…)

Pathologists and clinical laboratory managers can expect to see an expansion of genetic testing in the wake of the Supreme Court’s decision in the Myriad case
Pathologists and clinical laboratory professionals got a major victory on June 13. That’s when the United States Supreme Court (SCOTUS) ruled 9-0 to end the 30-year-old practice of awarding patents on human genes. The unanimous decision invalidates certain hotly contested patents held by Myriad Genetics, Inc., (NASDAQ: MYGN) on the BRCA1 and BRCA2 genes.
Moreover, this Supreme Court decision also opens the doors to other medical laboratories to develop their own diagnostics around the BRCA genes and compete for breast-cancer testing market share. (more…)
